"There are games in chess won by the same style, same manner, same number of moves and even same moves. There are doubles. I think any chess master has his own experience with these doubles."
- Ljubomir Kavelek, quoted in James Plaskett's, Playing to Win
A while back I wrote about this on my club blog (http://streathambrixtonchess.blogspot.com/2006/10/doubles.html) giving a couple of examples played OTB 18 months apart against the same opponent.
The two games were identical until move 9 and could have become identical again at move 16 had Black played a different move in the second game. Although the position on the board then became different the themes that emerged were very similar in both games.
I thought then - and now - that this is very rare.
Here at RHP I've now completed 20 games and have another half dozen on the go at the moment. So far the longest I've had a game match another exactly is 10 moves - and this despite the fact that the vast majority of my games have started with the same opening system..
I'm wondering if my experience is common or unusual.
Do your games follow similar patterns or do they vary early on?
What's the longest double you've had so far?
